Technical Field

[0001] The utility model relates to the technical field of hydraulic pipeline air tightness testing, in particular to a pipeline air tightness testing device with a protection function. Background Art

[0002] Hydraulic pipes are oil transport pipelines used in hydraulic equipment. Before they are put into use, they need to be tested for air tightness using an air tightness tester.

[0003] The air tightness tester, also known as the leakage tester, can be used for sealing tests of bottles, tubes, tanks, etc., especially in hydraulic pipelines. The air tightness tester can greatly improve the detection efficiency of the staff.

[0004] Most of the air tightness testers on the market usually need to connect the external air pipe to the air pipe joint on the device before they can be put into use. When the air tightness tester is not put into use, the air pipe joint is often in an exposed state and lacks a device to protect the joint. If impurities invade the inside of the air pipe joint, it may cause the air pipe joint to be blocked, resulting in damage to the equipment. Utility Model Content

[0023] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a pipeline air tightness testing device with a protective function, comprising an air tightness tester 1 and a display screen 11, the air tightness tester 1 is provided with a display screen 11, a plurality of tracheal joints 2 are fixedly mounted on the outer wall of the air tightness tester 1, a protective mechanism 3 for protecting the tracheal joints 2 is provided on the back of the air tightness tester 1, and the protective mechanism 3 can prevent impurities from invading the interior of the tracheal joints 2, and an anti-collision mechanism 4 is provided on the air tightness tester 1, and the anti-collision mechanism 4 can prevent the display screen 11 on the air tightness tester 1 from being hit.

[0024] The above-mentioned protection mechanism 3 includes a protection cover 31, a slide plate 32, a bolt 33, and a rubber pad 34; the protection cover 31 is slidably connected to the outer wall of the air tightness tester 1. When the air tightness tester 1 is not in use, the protection cover 31 is pushed toward the end close to the trachea joint 2 so that the protection cover 31 covers the trachea joint 2. The slide plate 32 is slidably connected to the inner wall of the protection cover 31. The side wall of the slide plate 32 is fixedly installed with a rubber pad 34. The slide plate 32 cooperates with the rubber pad 34 to seal the trachea joint 2. At the same time, the trachea joint 2 can be protected in cooperation with the protection cover 31 to prevent impurities from invading the interior of the trachea joint 2 and causing the trachea joint 2 to be blocked. The bolt 33 is threadedly connected to the inner wall of the protection cover 31, and the bolt 33 penetrates the protection cover 31 and is rotatably connected to the side wall of the slide plate 32. The bolt 33 is rotated so that the bolt 33 pushes the slide plate 32 toward the end close to the trachea joint 2, and the slide plate 32 drives the rubber pad 34 to fit tightly against the surface of the trachea joint 2.

[0025] The above-mentioned anti-collision mechanism 4 includes a baffle 41, a limit rod 42, and an inclined groove 43; the baffle 41 is slidably connected to the outer wall of the air tightness tester 1, and the limit rod 42 is fixedly installed on the side wall of the baffle 41. The baffle 41 is driven by the limit rod 42 to slide downward synchronously, so that the baffle 41 can cover the display screen 11 on the air tightness tester 1 to prevent the display screen 11 from being hit and then damaged. An inclined groove 43 is opened on the protective cover 31, and the end of the limit rod 42 away from the baffle 41 passes through the inclined groove 43, and the limit rod 42 is fitted with the penetration point of the inclined groove 43. When the protective cover 31 moves toward the end close to the trachea joint 2, the inclined groove 43 will squeeze the limit rod 42, so that the limit rod 42 fits on the inner wall of the inclined groove 43 and moves downward.

[0026] Working principle: When the air tightness tester 1 is not in use, push the protective cover 31 toward the end close to the trachea joint 2 so that the protective cover 31 covers the trachea joint 2, and then rotate the bolt 33 so that the bolt 33 pushes the slide plate 32 toward the end close to the trachea joint 2, and the slide plate 32 drives the rubber pad 34 to be tightly attached to the surface of the trachea joint 2. The slide plate 32 cooperates with the rubber pad 34 to seal the trachea joint 2. At the same time, the protective cover 31 can protect the trachea joint 2 to prevent impurities from invading the interior of the trachea joint 2 and causing the trachea joint 2 to be blocked.

[0027] When the protective cover 31 moves toward one end close to the trachea connector 2, the inclined groove 43 will squeeze the limiting rod 42, so that the limiting rod 42 fits the inner wall of the inclined groove 43 and moves downward. At the same time, the limiting rod 42 will drive the baffle 41 to slide downward synchronously, so that the baffle 41 can cover the display screen 11 on the air tightness tester 1 to prevent the display screen 11 from being hit and damaged.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
